There are many ways we could go to integrate real-time Indego station info. My first thought is:
Download the real-time information on the server each minute (or more often)
Cache the last 15 minutes of data
Preprocess to get the number of bikes checked out or returned at a given station within the last 15 minutes
Use that info to set the frequency of flashes for each station (so that they all have different periods/frequencies and it looks like twinkling ... maybe)
